kserv: bug-fix (in 9.1.0, this module wasn't working correctly with 1.1 or 1.2 exe, if there was no Edit Data. And also could cause crashes)

updated documentation, new installer

lodmixer: support for "active player" LODs.

"I re-wrote the Installation instructions in the docs. Please read it, because the recommended way of installing the kitserver and using it with the game has been changed slightly. If you read the "Installation / Removal" section of the manual, it will save you a lot of time later. The manual is included inside kitserver, and also is available online at http://kitserver.ath.cx/docs/"
